Transcription

1 DC POWER SUPPLIES DNX 110/220 V ISO 9001 Power supply systems DNX are dedicated to supply the equipment which needs for its operation direct voltage 110 / 220, with emphasis on maximum reliability and monitoring. Modular design of parallel modules of power up to 32,4kW 9 pcs. these power DC modules, enables also additional extension of the power with redundancy. The unit with cabling is always ready for insertion of all modules max. into 3 racks. Field of application: - power industry (distribution points, self-consumption, switching elements of distribution point) - railways (converter stations and supplying stations) - industry (technologies using the supply 110 and 220 V) Main characteristics POWER MODULE: processor control on DSP basis modular design digital communication interface CAN possibility of parallel shifting PFC Power Factor Corrector adjustable output voltage and current in wide range operating in various modes according to configuration of whole system visual indication of operating status possibility to upgrade firmware via USB plug & play possibility to remove or add module without turning the module off, or without system turn off no need for additional configuration or adjustment of the module before or after connection into the system auto detection of voltage version of system, where the module is inserted. SYSTEM: processor control on DSP basis advanced monitoring and functions high reliability modular design N + 1 redundant control possibility to add up to 3 control modules into one system digital CAN bus for the control of parallel cooperating power modules high maintenance comfort control panel with LCD display sound and visual indication 6 signalling relays optional configuration of statuses possibility of monitoring via USB possibility of monitoring via Ethernet max 9 pcs. of power modules max. system power 32,4 kw max. output current 234 A (power supply mode, charger) max. output current 200 A (mode of battery supply) possible to connect 2 independent battery strings installation in 19 cubicles

2 Control and monitoring Whole system is supervised by microprocessor control unit MDR001 with LCD module MDL001 (on door) or MDL002 (19 / 1U). The unit is dedicated to control and monitor the direct back-up power supplies with digital control of power modules with output voltage 110 / 220V. The control system and used circuits ensure not only basic, but also detailed control and monitor actions. It ensures whole system monitoring, battery care, watching of adjusted values of currents and voltages, control and monitoring of power modules, saving history of events, and much more. In cooperation with module MBZ, the control unit optimises battery charging, gives the command for switch off when deep discharge appears. Batteries are external or internal and the power supply facilitates the connection of 2 independent strings. Charging characteristics can be U, IU, IUoU, USER. USER is user defined characteristic in 10 points. All charging characteristics are with temperature compensation of maintenance voltage. Communication with user via dry contacts relay, serial interface USB, is enabled by SNMP adapter, LAN adapter or connection of GSM modem. DC power modules Modules are AC/DC rectifiers with mains input and direct output voltage 110 / 220 V. In cooperation with processor control module MDR001, after connection to mains and supplied equipment, these ensure supplying of connected units and optimal battery charging if batteries are included. Power modules can also work independently, after fail of control module. Power modules are designed for 19" racks. Cooling is forced; front rear side air flow. At parallel shifting of power modules, the sharing of current is not master/slave, but redundancy is absolute. When failure of any power module occurs, the remaining power modules take over the load and the system is able to cover fully the demand of connected equipment. Modules are managed fully digitally on the basis of DSP processors. D D

Cooling of cubicles is forced air flow from front side to rear side. Front and rear door are perforated and there has to be ensured adequate space for air circulation. Batteries can be provided as internal inside system cubicle, or external in battery cubicle or shelf. Connection of input and output cables to system DNX is made from the bottom side of the cubicle.
